Consider the following linked list C++ code: - struct node { int data; struct node *next; }start = NULL; struct node *new_node; Select one: a. new_node=(struct node *)malloc(sizeof(struct node)); b. Non of Above с. new_node=(struct node)malloc(sizeof(struct node)); new_node=(struct *)malloc(sizeof(struct node)); d. new_node=(struct node *)malloc((struct node));

Create a user-defined function called duplicates. This function will check to see if a singly linked list contains nodes with the same data stored. If any duplicates are found, return the value 1. Otherwise return 0. You may use the following typedef structure. typedef struct node_s{ int data; struct node_s * nextptr; }node_t;

In C++.

T/F: All Linked Lists must have head node.

Assume a linked list contains following integers: 7, 2, 9, 5, 8, 3, 15 and the pointer head is pointing to the first node of the list. What will be the value of variable a after the following statements are executed: Node<int> *curNode=head; Node<int> *aNode; int s; while(curNode!=NULL){ {       aNode=curNode;       curNode=curNode->getNext(); } s=aNode->getItem();   A. 15 B. 3 C. 7 D. 2

Java/Data Structures: The Java Class Library implementation of the interface list return null when an index is out of range.  True or False

Project 2: Singly-Linked List The purpose of this assignment is to assess your ability to: ▪Implement sequential search algorithms for linked list structures ▪Implement sequential abstract data types using linked data ▪Analyze and compare algorithms for efficiency using Big-O notation For this assignment, you will implement a singly-linked node class. Use your singly-linked node to implement a singly-linked list class that maintains its elements in ascending order. The SinglyLinkedList class is defined by the following data: ▪A node pointer to the front and the tail of the list Implement the following methods in your class: ▪A default constructor list<T> myList ▪A copy constructor list<T> myList(aList) ▪Access to first elementmyList.front() ▪Access to last elementmyList.back() ▪Insert value myList.insert(val) ▪Remove value at frontmyList.pop_front() ▪Remove value at tailmyList.pop_back() ▪Determine if emptymyList.empty() ▪Return # of elementsmyList.size() ▪Reverse order of…

Having trouble with creating the InsertAtEnd function in the ItemNode.h file below.  "    // TODO: Define InsertAtEnd() function that inserts a node    //       to the end of the linked list" Given main(), define an InsertAtEnd() member function in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts  ------------------------------------------------------- main.cpp -------------------------------------------------------- #include "ItemNode.h" int main() {    ItemNode *headNode;  // Create intNode objects                                                       ItemNode *currNode;    ItemNode *lastNode;     string item;    int i;    int input;     // Front of nodes list                                                                             headNode = new ItemNode();    lastNode = headNode;     cin >> input;     for (i = 0; i < input; i++) {        cin >> item;…

With Head node or not? statement is: if(p->rlink != first) p = p->rlink; O a. It is a Doubly linked list without Head node. O b. It is a Doubly linked list with Head node.
